Tested that patch:
1. The driver no longer automatically loads, I had to manually modprobe it.
This must be some other problem not related with patch.
Yes, will check this again shortly.
2. After loading, I get this (keep getting these)

You can remove line
ERROR(rt2x00dev, "Data pending\n");
from rt2800_txdone to stop seeing this. It's kinda interesting
how frequent this happens.
It seems to happen somewhat often; e.g. if you apt-get install pkg, it
will popup 3-4 times.
No crash yet, but bad ping again too (always with the rt2800usb) driver:

I think patch could have site effect to not run tx queue while we have pending
data on it. Do you have such ping times always (i.e. after a 5 minutes, 10
minutes, 20 ... ) or just randomly?
Randomly.

Still working so far though, at least the box has not crashed yet, but I'll
give it some more time.
